The DW750 Second Unibus Interface was an optional extra UNIBUS adapter for the VAX-11/750; it connected to the CPU/Memory Interconnect (CMI). It was very similar to the UI750, but did not contain the additional functionality (console, etc) of the UI750.

It was implemented on one extended hex card, the L0010 Unibus Adapter (UBA or SUB), which mounted in the VAX-11/750 backplane in one of the three CMI option slots. A VAX-11/750 could have up to one DW750 Second Unibus Interface.
